the same.

My invention relates to an improved ma chine for performing variousagricultural op erations, such as raking hay, gathering manure,cultivating, plowing, ditching, or level' ing land, grading roads, etc.

The object of my invention is to provide a machine of this characterwhich will be simple in construction, comparatively inexpensive toproduce, durable in use, and well adapted for various purposes.

With this and other objects in-view the invention consists ofcertain'novel features of construction, combination, and arrangement ofparts, as will be more fully described, and particularly pointed out inthe appended claims.

In the accompanying drawings, Figure 1 is a perspective view of myimproved machine. Fig. 2 is avertical front to-rear sectional yi'ew Fig.3 is a horizontal sectional view. Fig. 4 is a front-elevation of themachine, showing the same provided with shovels for cultivating, &c.Fig. 5 is a similar view Showing the machine provided with a scraper forleveling, grading, &c. Fig. 6is a detail sectional View taken on theline 6 6 of Fig. 5.

In the embodiment of my invention, as illustrated in the drawings, thenumeral 1 denotes a vertically-disposed central frame, preferablyrectangular in form, having vertically-disposed side or end frames 2,pivotally secured to its ends and supporting it above thegro'und. Saidside supporting-frames are also preferably of rectangular form and arenormally disposed at right angles to the central or main frame 1. Eachof said side supporting-frames comprises a bottom beam 3,which forms arunner; a top beam 4, connecting uprights 5, and a diagonal brace 6. Aseat 7 and a foot-rest 8 are provided on each of the side frames-for anop- Application filed December 15, 1903- Serial No. 186,304. (No model.)

erator who drives the draft animal or animals attached to a tree ordraft element 9, secured by a chain or other flexible connection 10 tothe outer ends of said frames 2. The projecting rear ends of the'top andbottom beams 4 and 3 are pivotally connected to the ends of the upperand lower longitudinal beams 11 and 12 ofthe center frame 1 by verticaltie bolts or rods 13, so as to permit said side frames to be swung toany desired angle in a horizontal plane. If it is desired,thesesupporting-frames 2 may be mounted upon wheels in any suitable mannerand provided with suitable braking devices for controllingthe speed ofthe machine in going downhill.

The upper and lower longitudinal beams 11 and 12'of said center frame 1are connected adjacent-to their ends byvertical uprights 14,and saidframe'is braced at each of its corners by angle-brackets 15, as shown.Mounted to slide verticallyin the frame 1 upon the tie-rods l3 and theuprights 14 is a longitudinal beam 16, which may be adjusted and held inits adjusted position by any suitable-means, but preferably by swivelingadjacent to its ends vertical screw-shafts 17, the upper portions ofwhich work through screw-threaded openings in the upper beam 11 and areformed upon their upper ends with crank-handles 18, by means of whichtheoperators may readily operate the screw-shafts to raise or lower thebeam 16, as will be readily understood.

As shown in Fig. 1, the adjustable beam 16 is provided on its front sidewith a series of teeth 20,-which may be straight, curved, or of anysuitable form and construction for raking hay and performing likeoperations. Each of said teeth preferably comprises a pointed lower end21 and a forked or bifurcated upper'end, the arms of which are aperturedor formed with eyes 22, which aline with eyebolts 23, spaced along thebeam 16 and adapted to receive a locking-rod 24, which passes throughsaid alining eyes 22 and 23 to pivotally connect the teeth to saidadjustable beam 16, allowing said teeth to be swung in a vertical plane.By pivoting the teeth in this manner any desired number of those mountedon the rod 24 may be swung down for use, those not-in use restingagainst the upper beam 11,.

as shown by the dotted lines in Figs. 1 and 2, and secured to the sameby books 25 or any other suitable fastening devices. The teeth which arein use bear against the front side of the lower beam 12 and are therebysupported at an angle, as shown.

In Fig. 4 of the drawings I have shown the lower ends of each of theteeth 20 provided with a shovel 26, by means of which the ground may becultivated, as will be readily understood. Owing to the detachablepivotal connection of the teeth, any number of shovels may be used, andthey may be arranged at any desired distance apart. Instead of usingsmall shovels, as shown, large ones may be employed for plowing,ditching, and other purposes.

In Figs. 5 and 6 I have shown a scraper 27, secured upon the adjustablebeam 16. Said scraper, which is preferably made of metal,

is of slightly less length than the center frame 1 and has secured toits rear side two or more braces 28, having their upper ends projectingabove said board and formed with hooks 29, which engage said, beam 16.Bolts or pins 30 are preferably used for detachably securing them uponthe beam, as shown in Fig. 6. Instead of using a flat scraper-blade, asshown in Figs. 5 and 6, a large bowl-scraper or a scralping device ofany desired form may be usec.

If it is found desirable, I may use rake-teeth 35, as shown in Fig. 6,in connection with the teeth 20, previously described. These teeth 35are secured to the rear of the beam 16, so as to be raised and loweredwith the latter, and they are of unequal length to form two or morerows. If desired, they may also be provided with cultivator-shovels.

The operation and advantages of my invention will be readily understoodfrom the foregoing description, taken in connection with theaccompanying drawings. It will be seen that when the side frames 2 areat right angles to the center frame and the draft-animals draw themachine forwardly upon the runners 3 of the side frames theraking-teeth, cultivator-shovels, scraping-board, or other devicecarried by the center frame will be moved over the ground to perform'thedesired work. By adjusting the screws 17 the device carried by thecenter frame may be readily raised or lowered to vary its operation.Owing to the pivotal connection of the side frames with the centerframe, they may be swung so as to draw the center frame forwardly at anydesired angle, which is of particular advantage in grading a road.

It will be understood that I do not limit myself to the adjusting meansfor the beam 16, (shown in the drawings,) since any suitable mechanismwhich will accomplish this result and which may be controlled by theoperator when the machine is in motion may be provided. The frame 2 mayalso be mounted upon wheels, as previously stated, and numerous othertools or implements than those mentioned may be used upon the machine.

Various other changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a machine of the character described, the combination of a centerframe carrying an acting implement or device, side supportingframespivotally connected to said center frame, an implement-supporting beamcarried by the center frame, and means for vertically adjusting saidbeam upon said frame.
